BARNES, on ons MOINES, Iowa v v DISPENSER Application led May 5,

The object of my invention is to provide I a dispensing apparatus for the dispensing of semi-hard substances such as soap, vanl ishing cream, tooth paste and the like, which ordinarily are packed in tubelike containers commonly known as collapsible tubes.

Still a further object is to provide an air tight chamber in which the collapsible tube with its contents is mounted and'tliereafter 1o to maintain within the chamber or compartment, air under pressure so that the contents within the tube willbe held under a constant pressure.

Still a further object is to 'provide a Control valve in communication with theI contents of the collapsible tube so that when the V control valve isopen, the pressure around the collapsible tube will tend to-orce the contents therefrom through the valve controlled Still a further object is t rovide .an adaptor. within the container w ich is arranged to project into the `discharge openin .ofthe collapsible tube and to thereby threa the interior of the discharge opemng onto the adaptor for providing a tight connection between the adaptor and the collapsible tube, the adaptor being so arranged that discharge openings of various sizes may be connected thereto so thatthe device is uniform in its application. p A

Still another object is to provide vwithin the container, a pump structure wherein the fully set forth, pointedout in'my claims and Y illustrated in the' accompanying drawings, in

Figure 9 isa detail section l view through the lower end of the pum structure; and Figures 10 and 11 are iagnammatic views of the 'sealing ring in plan elevation illustrating howit connects the parts shown in Fi res 6 and 7 together.

n thev accompanying drawings I have used the reference character A to indicateV enerally a di nsing container which is ormed of a hol ow base element 10 and an upper capv member 12. The cap member 12 is adapted to coact with the upper end of the base element 10 and -to be detachably connected thereto by means of a sealing ring 14.

The upper end of the base element 10 is portion 16 so as to formed with a contracted provide ashoulder 18. T e contracted portion` 16 or neck as it may be properly termed, is provided with a pair of upstandin flan es 20 as clearly illustrated in Figure of ne drawings.

,f The cap or closure member 12 is formed with a contracted portion4 22 thereby providing a shoulder 24. Dowiiwa'rdly extendin anges v26 are mounted upon the contracte ortion 22 and extend partially below the ower edgethereof as clearly shown in Figure 6 of the drawings.` y

. The sealing'ring 14 is arranged with a pair of lower tapered mturned pro] ections 28 and pa pair of upper inturned proyections 30.

The lower projections 28 have their upper surface tapered or inclined so that-,when the aling ring is brought into contact with loothe members 10 and 12, and then rotated, it will cause the parts to be securely held together. The tapered extensions 28 fit in below the upstanding anges 20 on the element 10.

A rubber gasket or ring 32 is interposed between the lower edge of the cap member 12 and the upper end ofthe element 10. The entire container A may be said to consist of the base element 10, the cover-member 12 and the sealing ring 14. An air tight compartment or container is formed in the manner just described.

Formed upon the cover member 12 is a boss 34 having a screw threaded opening 36 therein arranged to receive a valve element B. The valve element B is provided with a screw threaded connection adapted to coact with the screw threads 3G. The valve element B includes further, a downwardly extending support or nozzle 38.

A valve seat 40 is formed within the valve member-B and is adapted to coact with a valve member 42 carried by a valve stem 44. A finger engaging piece 46 is secured to the free end of the valve stem 44 and is adapted to have a coil spring 48 rest thereagainst. The spring 48 has one end resting against the body of the valve member B and normally tends to hold the valve member 42 against its seat 40.

Inward movement of the valve member 42 against the action of the spring 44 will openv the passageway 50 within the boss 34 so that it is in communication with the opening in the nozzle or spout 38. Within the cover member 12 on the underside thereof, I mount an adaptor 52. The adaptor 52 is tapered and is provided with sharp screw threads 54 so that when a collapsible' tube or the like, 1s mounted upon the adaptor 52, the sharp threads will pierce the soft metal forming the discharge end of the collapsible tube and thus the collapsible tube will be securely held onto the adaptor 52.

An ordinary collapsible tube 56 is shown in Figure 2 of the drawings within the container A and its discharge end or neck 58 has the lower end of the adaptor 52 projected therein.- The adaptor cuts its own threads within the neck 58 of the tube 56 and by rotating the tube 56 a few times when it is being installed in position, enables the tube to be properly connected or mounted within the container A.

In order to place the collapsible tube 56 within the air tlght container under pressure sufficient to cause the contents to be discharged therefrom when the valve member 42 is unseated, I provide a pump structure C. The ump structure C has its casing or cylinder ormed integral with the base element 10 and includes a piston 60 mounted upon the rod 62.

The lower end of the base element 10 adjacent the pump structure C, terminates above the bottom of the major portion of the element 10 so that the head 64 upon the piston rod 62 may be received within the portion formed by arranging the lower end of the pumping structure C above the bottom of the major portion of the element 10.

The piston rod 62 is formed with a contracted neck 66 which may be shifted to one side for allowing the plug 68 to be partially received therein, thus locking or holding the piston rod 62 against any undesired movement when the device is not in actual use, that is, during the pumping operation.

The upper end of the pump structure C includes an ordinary one way valve mechanism 70 which allows air from within the pump structure to be discharged into the interior of the container A.

It will be understood that any type of pump structure may be used and that I have shown one form which is convenient and practical for use in connection with a dispensing apparatus of the kind herein disclosed.

The pump structure is arranged to be operated and when operated places the collapsible tube within the container under pressure. The pressure may be built up sufliciently to practically insure all of the contents of the container to be discharged before the pump structure need be operated.

The valve member B may be provided with a pair of outturned linger engaging ears 72 which makes it convenient and easy for placing two of the four fingers over the ears 72 and then using the thumb to press against the linger 46 which controls the valve member 42 for moving it to open position. The collapsible tube being under constant air pressure will tend to have its contents forced therefrom and upon opening of the valve member 42, the contents will immediately iiow from the nozzle or spout 38.

The valve member 42 is so arranged that the pressure of the contents in back thereof will tend to hold the valve member 42 in its seated position thus insuring the valve at all times to be properly seated. The spring 48 serves to quickly return the valve member after it has been manually operated to open position.

Practical operation The practical operation of my device includes the disconnecting of the cover member from the body portion of the container and taking any suitable semi-hard substance and fitting the neck thereof onto the adaptor 52.

After this has been accomplished, the tube is mounted within the base element 10 and the sealing ring 14 is applied and given a quarter turn. This causes the collapsible tube 56 to be entirely surrounded and mounted within an air tight compartment.

It will be noted that by' providing a tapered screw threaded adaptor, that necks of collapsible tubes of various sizes ma be used and sealed to the adaptor. It will further understood that collapsible tubes of a commercial nature vary in size and that the discharge openings of the tubes also vary in diameter and by providing a tapered screw threaded adaptor, I am able to place the neck of the tube over the adaptor and form screw threads on the interior of the neck which screw threads will lit the screw threads on the ada tor.

e pump structure() is then voperated a suicient number of times to fill the container A with air under pressure. Thereafter manu- Some changes may be made in the construcl tion and arran ment -of the Barts of my device without eparting from t e real spirit and purpose of my invention, and it is myA intention to cover by my claims, any modified forms of structure or .use of mechanical equivalents, which may be reasonably included within their scope. j
